A loop formation of Meckel's diverticulum: a case with obstruction of the ileum

An adult case of obstruction of the ileum caused by a loop formation of Meckel's diverticulum is described. The patient, having severe abdominal pain and vomiting, was diagnosed as having ileus. A roentgenogram with a contrast medium showed severe obstruction at the mid part of the ileum. From findings of elective laparotomy, adhesion between the inflammatory end of Meckel's diverticulum and the corresponding mesenterium had formed a loop, which had clasped the distal part of ileum. We here warn that Meckel's diverticulum forming a loop is a cause of obstruction of the ileum in adults.
